This guide is the list an integrator or a salesperson works through before a permanent LED wall is quoted: the pitch from the viewing distance, the size in whole cabinets, the power in house circuits, the heat, the weight and the depth, the data path and the processor, and the documents the client and the trades need. Every item is a figure the planner derives from the panel datasheet.
The industry convention is one metre of minimum viewing distance per millimetre of pitch, comfortable at two to three times that. A boardroom seen from 2 m wants 1.2 mm or finer; a lobby seen from 3 to 4 m works at 1.5 to 2.5 mm; a hall seen from 8 m is fine at 2.5 to 3.9 mm. Finer pitch costs more per square metre, so the nearest realistic viewer sets it, not the furthest.
The viewing distance calculator gives the minimum, comfortable and acuity distances for any pitch, and the planner picks the nearest published panel at the pitch you choose.
A wall is a whole number of cabinets, and the cabinet decides the sizes you can build. A 500 × 500 mm cabinet builds 16:9 at 16 × 9 cabinets, 8.00 × 4.50 m; a 608 × 342 mm 16:9 module builds 16:9 at any count, which is why install series come in that format: 6 × 3 Sharp modules are 3.65 × 1.03 m at 3,840 × 1,080 px. Decide the format from the content, then the count from the wall, then read the resolution off the cabinet.
The resolution is the pixel count of the cabinet times the count, and it is what the media player has to deliver. A screen at 3,840 × 1,080 px is a UHD source cropped, and the pixel map says where each screen sits on the processor canvas.
Circuits are sized on maximum draw at 80% derate: a 16 A / 230 V circuit carries 2,944 W, which is 17 cabinets of a 170 W panel or 84 modules of a 35 W one. The planner lays the circuits over the wall as strings that follow the cabinet connectors, counts them, and spreads them over the three phases in turn; the electrician assigns the final split at the board.
Give the electrician typical and maximum draw, the circuit count and the phase split, and the note that the circuits come from the building’s distribution board rather than a touring distro. Inrush current is not published on the sheets, and the breaker type is the electrician’s choice.
The heat load equals the electrical draw: typical draw for the continuous cooling design, maximum for the worst hour, in kilowatts and BTU per hour. The heat guide has the figures per square metre and a worked wall; the system sheet prints both figures for every screen.
Install panels weigh 22 to 42 kg per square metre from the sheets, the frame adds to it, and the structural engineer signs off the wall behind. Cabinet depth is 49 to 99 mm plus the frame; front-service modules sit close to the wall, rear-service cabinets need an access gap. The weight guide has the figures and the reasoning.
A rental show runs one data path per run and carries a spare cable; a permanent install runs looped data, an A path in and a B path back, so that one failed cable or port does not black a section of a lobby wall for the week it takes to get a technician there. Looping doubles the port count, which decides the processor: a 6 × 3 wall of 0.9 mm modules that needs 12 ports of a VX1000 single-path needs 24 looped.
Copper data runs are good to 100 m including the service loop; beyond that the run is fibre. Cable tags, one per cable with both ends named, are how the wiring survives the handover.
The processor carries the pixels, and its sheet publishes a canvas limit and a per-port limit. A wall wider or higher than the canvas is split across processors, and the planner says so. Fine pitch multiplies pixels: a 3.65 × 1.03 m wall at 0.9 mm is 4.1 megapixels, which is more processor than a 8 × 4.5 m rental wall at 2.8 mm.
Brightness is chosen against the room: install modules at 600 nits for a controlled lobby, 1,500 nits for a bright atrium, 5,000 nits outdoors, all from the sheets. Refresh rate matters when the wall is filmed; the on-camera guide covers it.
A quote or a client needs four things from the planner: the system sheet, one page per screen with size, power, heat, structure and signal; the cable tags for the installer; the pixel map for whoever builds the content; and the install list, the bill of materials with spares and house circuits. All four come from the same description of the wall, so a change in the size changes every figure on every page.
RigPlan does this arithmetic for you. Describe the screen once and it gives the circuits and phases, the heat, the weight and load, the looped data and the processor, on one sheet for the quote. Free on screen, with no sign-up; the installation planner says what it covers.
Plan an installSeen from 3 to 4 m, 1.5 to 2.5 mm. The convention is one metre of viewing distance per millimetre of pitch as the minimum, and two to three times that as comfortable; the nearest realistic viewer sets the pitch.
Yes. Looped A and B paths keep the wall lit through one failed cable or port, which on a permanent install is the difference between a service visit and a week of a dark section. It doubles the port count and often the processor size, and the planner switches it on for install jobs.
Typical and maximum draw in kilowatts, the circuit count at the site’s rating, the phase split, and that the circuits come from the building’s board. The system sheet prints those; the breaker type and the cable sizing are the electrician’s.
